What to Know
Van Dyke is charged with murder in the shooting death of 17-year-old McDonald nearly four years ago
The Chicago police officer was captured on dashcam video shooting McDonald 16 times the night of Oct. 20, 2014, on the city's Southwest Side
Van Dyke entered a plea of not guilty
But in the fourth day of defense testimony in Van Dyke's murder trial, a retired CPD weapons instructor testified that officers are trained to do that if reasonable and necessary.
"You shoot until the threat is eliminated," said retired officer Nicholas Pappas. "There is no telling what that could be. It's no telling how many rounds it could take to do that."
After the shooting, Van Dyke reloaded his weapon, a move the instructor also said was part of the training.
"To stand there with an empty weapon is a big problem," Pappas said.
But prosecutors pressed Pappas on whether such a shooting should be considered "reasonable or necessary."
"This is the deadliest weapon in his arsenal?" Prosecutor Daniel Weiler asked.
"Yes," Pappas said.
"And the defendant is taught there could be criminal and civil consequences for the use of that weapon?" Weiler said.
"Yes," Pappas said.
"And he is taught to utilize that weapon with restraint?" Weiler said.
"Yes," Pappas said.
Defense attorneys have so far presented nearly two dozen witnesses, but have given no indication if Van Dyke himself will take the stand.
Attorneys said the previous day that Van Dyke never should have been charged with murder because of an Illinois law that protects peace officers trying to arrest fleeing felons.
McDonald’s great uncle said he watched Wednesday as witnesses testified to alleged violent incidents involving McDonald as a juvenile.
"It is an unjust ploy to paint Laquan McDonald as the perpetrator," Rev. Marvin Hunter said. "He is a victim. He is the victim in this case. He is not on trial."
Dr. Jeremy Stayton, who treated McDonald the night he was shot, said the teen had no blood pressure, no respiration and no pulse. A wound to his pulmonary artery, Stayton said, caused McDonald to lose more than half the blood in his body.
"The chances of him surviving are very low in any case," Stayton said, then answering what the chances would have been, "I don’t know if anyone has ever done a paper on it, but I would say less than 1 percent."
On Tuesday, jurors were shown a recreation of the fatal shooting from the officer's perspective that was based on laser analysis of the scene and looked like it was taken straight from a video game.
According to defense attorneys, the video showed that McDonald was closing the distance between himself and Van Dyke before the officer opened fire. Prosecutors have argued dashcam video shows McDonald appearing to walk away as Van Dyke shot the teen 16 times on Oct. 20. 2014.
Van Dyke was charged with six counts of first-degree murder more than a year after he shot McDonald on the city's Southwest Side. He entered a plea of not guilty.
Special prosecutors rested their case against Van Dyke Thursday after calling 24 witnesses over three and a half days.
So far in the trial, the jury saw dashcam video of the shooting, graphic autopsy images of the more than a dozen gunshot wounds on the body of McDonald, video recreating the shooting from Van Dyke's point of view and video showing 16 gunshots in under 14 seconds.
They have also heard testimony from several Chicago police officers and witnesses at the scene, seen the weapon Van Dyke used, and watched as FBI specialists demonstrated the shooting.
